Limiting the accretion disk light in two mass transferring hot subdwarf binaries
Kunal Deshmukh, Thomas Kupfer, Pasi Hakala +6
We report the results from follow-up observations of two Roche-lobe filling hot subdwarf binaries with white dwarf companions predicted to have accretion disks. ZTF J213056.71+4420…
The origin of the vanishing soft X-ray excess in the changing-look Active Galactic Nucleus Mrk 590
Ritesh Ghosh, Sibasish Laha, Kunal Deshmukh +3
We have studied the nature and origin of the soft X-ray excess detected in the interesting changing-look AGN (CLAGN) Mrk~590 using two decades of multi-wavelength observations from…
GROWTH on S190426c II: GROWTH-India Telescope search for an optical counterpart with a custom image reduction and candidate vetting pipeline
Harsh Kumar, Varun Bhalerao, G. C. Anupama +17
S190426c / GW190426_152155 was the first probable neutron star - black hole merger candidate detected by the LIGO-Virgo Collaboration. We undertook a tiled search for optical count…
India's first robotic eye for time domain astrophysics: the GROWTH-India telescope
Harsh Kumar, Varun Bhalerao, G. C. Anupama +35
We present the design and performance of the GROWTH-India telescope, a 0.7 m robotic telescope dedicated to time-domain astronomy. The telescope is equipped with a 4k back-illumina…
X-ray observation of the Roche-lobe filling white dwarf plus hot subdwarf system ZTF J213056.71+442046.5
S. Mereghetti, N. La Palombara, T. Kupfer +9
ZTF J213056.71+442046.5 is the prototype of a small class of recently discovered compact binaries composed of a white dwarf and a hot subdwarf that fills its Roche-lobe. Its orbita…
